I had a problem like this on my 88 CRX. your driving in any gear, you step on the gas and the car is in gear and it revs before excelerating. Was a clutch back in the 90's on my CRX. does any one think it may just be dirty brake fluid in the master and brake system. I ask because my Honda Accord did this and i had to bleed the slave cylinder. The focus has no slave cylinder any ideas it has been slowly getting worse and it may not make it another day!
